I need help identifying this part.
i have a 74 2.0 teener. djet this part is beside the distributor (that is the orange piece with the clamp) and in front of the coil (the larger green wire.) the green wire from this part has a brown stripe..where does it go? where does the black wire to this part go? I am trying to identify the part but in the long run something is awry. not starting we have checked plugs (which are wet with fuel) we have changed them so there is fuel, a good fuel pump. so right now just seeing what could prevent this from starting and found this part and need to identify it. thanx for all your help. thanx so much will update when figured out the problem. I am sure we just dislodged a wire. stay tuned. 914luva |

Check the cylinder head temp sender. If it is open, then the computer thinks it is below -20 degrees F, so it dumps gas into the engine. Usually this results in fouled plugs and gas in the oil.
Most common cause is the connection between the sender and the harness. The plug will look like it is connected, even when it is not. |

I drove around for about a year bitching about a problem with surging that I swore was a bad TPS, only to find that the CHT sensor female connector wasn't actually pushed on to the male wiring harness connector, but was instead jammed between the plastic and the metal connector. Every time I hit a bump it would open and make the car jerk. I fixed it and my being a jerk was over. |

Every time I hit a bump it would open and make the car jerk. I fixed it and my being a jerk was over. The L-Jet and the D-Jet system use the exact same CHT, and connectors. So it can happen on any 914 with the stock FI. I did it on Betty's car. Chased the poor running and black smoke for 3 days before finding I didn't get that damned spade connector connected solidly. It would open circuit randomly. Drove me batshit crazy looking for the issue. This is the same sensor for a 911 Carrera 3.2. The resistance values in it are exactly the same as the 914 sensor. (IMG:http://www.914world.com/bbs2/uploads_offsite/www.autohausaz.com-1143-1476013429.1.jpg) Note that the connector on it is the same as an L-Jet fuel injector. Replace the stock sensor with this, and put an L-Jet fuel injector connector on the CHT wire (IMG:http://www.914world.com/bbs2/uploads_offsite/www.autohausaz.com-1143-1476013431.2.jpg) Then hook the other one to a solid ground. You will never have that spade connector issue again. |
